Algebra + fractions

WOW this forum is great just what ive been looking for.
Ive recently decided to do Electrical Engineering and ive found maths really hard since i have not done any bridging maths to help me with this =(

Anyway to the question, can anyone help me to solve this or direct me to a website that explains how to work with fractions.
